In this sentence, "Si tu tiens absolument à ce que je te lâche en pleine brousse, je ne vais pas me bagarrer." What purpose does à ce serve? Could it be taken out and only use "que" ?

[Maître Capello]

What purpose does à ce serve?

In the required sense, the construction of the verb is tenir à qqch/qqn.

Could it be taken out and only use "que" ?

No, you can't drop the preposition. It would totally change the meaning of the phrase.

tenir à ce que = to insist that / to be keen to
tenir que (old-fashioned) = to believe that / to maintain that
tenir de qqn que = to have heard from someone that
